HARROW ATTACHMENT FOR PLANTERS.

Specification of Letters Patent Patented Apr. 16, 1918.

Application led .Tune 20, 1917. Serial No. 175,947.

To all whom z' may concern.'

Be it known that I, GERHARD KETTMANN,a citizen of the United States,residing at Manning, in the county of Carroll and State of Iowa, haveinvented certain new and useful Improvements in Harrow Attachments forPlanters, of which the following isa speci fication. l

' This invention has for its object the provision of means whereby aharrow maybe attached to and drawn over a field in rear of a planter1 sothat the harrowing of the soil may be accomplished simultaneously withthe planting of the seed. Secondary objects of the invention are toprovide means whereby the harrow will be supported in its operativeposition and may be readily elevated when it is desired to turn a corneror objects as will incidentally appear in the course of the followingdescription are attained in mechanism ofthe characteristics illustratedin theaccompanying drawings and the invention resides in certain novelfeatures which will be particularly lpointed out in the claims followingthe Vdetailed de- In the annexed drawings: Y Figure 1 is a plan view ofa portion of' planter showing` my improved harrow attachment vconnectedtherewith;

Fig. 2 is a side elevation of the same;

F ig. 8 is a detail rear elevation of a portion of the harrow liftingand supporting mechanism;

Fig. 4 is a detail plan view `of 'the har- Y row.

Fig. 5 is a detail perspective view showing the connection between adraft bar and a runner.

The planter frame is indicated by the reference numeral 1 and may be ofany well known or preferred type, being supported upon ground wheels 2and equipped with mechanism actuated by the axle to operate the seeddropping mechanism.

In carrying out my invention, I secure to the side bars of the planterframe, adjacent the rear ends thereof, brackets 3 having a rock' shaft 4journaled their lower ends, said rock shaft extendlng across the rearYreached by the foot of the driver.

end of the planter frame and being equipped l with segments 5 on itsends, as shown. The

said segments have grooved peripheral surfaces, indicated at 6, andthese surfaces are flared or provided with diverging side flanges 7extending from the normally upper rear corner to the normally lowerforward corner thereof so as to accommodate the lateral movement of thesuspending devices S which are attached at their upper ends to the eyes.9 provided at the upper rear corners of the segments. 'Io one ofthe'segments, at the inner side of the same andat the upperV rear cornerthereof, I pivot the rear end of a link 10 which extends for wardly andhas its front end pivoted to the upper end of a foot lever 11 fulcrumedin any convenient manner upon the planter frame at such a point that itmay be easily This foot lever is extended below its fulcrum, asindicated at 12, so that it will be counterbal anced yand move easilyand without-undue exertion upon the part ofthe driver.

The harrows may be of any desired construction, but will generallyconsist of tooth bars 13 disposed transversely of the line of travel andin parallel relation and connected by braces 14. The harrow teeth 15Vwill be secured in the tooth bars and will depend therefrom so as toengage the surface of the ground in the usual manner. The tooth bars 13may, of course, be of any desired length but I have found itadvantageous to employ three bars with the front` bar shorter than and aconsiderable distance in advance of the other two bars. The bars willpreferably be constructed in sections having sockets 16' in theirmeeting ends to f receive coupling bars 17, retaining pins 18 beinginserted through registering openings 19 in the ends of the toothbarsand the couplings so as to retain the sections of the tooth bar inperfect alinement. This construction will facilitate storage oftheharrow and will also, when the harrow is in' use, hold the tooth barsin'perfect alinement and prevent relative movement of thev same.

To the front tooth bars, I secure the clevises 20 which projectforwardly. Draft bars 2l are pivoted at their frontends to the brachlets or 'hangers 22 secured to and depending from the planter frameandthese draft bars extend vdownwardly to a point just in adw van'ce of thefront tooth bar lfwhere-they are 'bent to provide shoulders 23 which :i

filo

Q ,Y Y neeaovo through the clevises 2O and thereby apply the draft ofthe machine to the clevises so that the harrows will be held closeto theplanter frame and will be drawn over the field lwithout strain upon thelifting` chains 8 which will generally be attached to the `draft barsand are so illustrated. Below'the shoulders 23, the draft bars areturned rearwardly to project under the tooth bars of the harrow, asshown at 2li, and upon these rearwardly turned portions, l pivot therunners 25 bypins 25. As indicated by dotted lines in F ig. 2 andshownclearly in Fig. 5, the rear ends of the draft bars extend beyond thepivot pins '25 into the front ends of the runners and thereby limit thedownward movement of the runners so that no matter how deep the harrowteeth may penetrate, the runners will only engage the top of the soilsufficiently to counteract llateral movement of the harrow and will notbury themselves in the earth so as to increase the draft. When the draftbars are raised the runners will of course be carried upwardly by theengagement of their front portions with the upper `sides of the rearLkends of the draft bars and consequently will aid in supporting theharrow in the elevated position. The said runners 25, may ride .upon thesurface of the ground and will thereby aid .in guiding the harrows andwill 'also tend to clear the harrow teeth of any .planter in the mannershown and above de-v scribed. As the planter is drawn overv thefield,.the harrow will, of course,v travel di- Y I rectly in rear of thesame. rlhe harrow will,

of course, .travel close behind the planter and will pulverize thesurface'soll and throw the same over the seed so that the cultivationtwill start simultaneously with theplanting. *.The lharrow will belprevented from va swayfing motion by reasonof the draft bars 21engaging' Ythe clevises 2O and as the said draft bars are rigid andpivoted for vertical movement only, lateral movement of the harrows willbe exceedingly slight. lf it be den isired to raise the harrows, thedriver presses 'forward upon the foot lever 11 and thereby exerts aforward pull through the link or v-1- c-'onnecting bar l0. which in turnacts upon the .segment 5 so as torock the shaft 4, the segment-s atlboth ends ofthe shaft being thereb` .rocked in unison to pull unwardand Y i l .fo'rward upon the chains 8 so that the har- -row willbelifted. 'lt Ymay sometimes be "desir-able to. provide the `har-rowswith la. saac'eanterbalaneetso ythan 'they willgmoreupthe same.-

wardly easily and will be supported in their upper position withoutexcessive strain upon the chains. The drawings show the counterbalancein the form of a weighted arm but the weight is not essential and may beomitted. ln actual practice it is desirable to have the arm so adjustedand of such length that vwhen the harrow is raised the arm will bearagainst the under side of the shaft l and thereby serve as a bracingsupport. for the harrow. lt may be noted that when the harrow has beenfully raised, as indicated by the dotted lines in'FigzQ, the

vlever 11 and the link or connecting bar 10 the raised position and theteeth will not be apt to come in Contact with the ground. l.When it isdesired to lower the harrow 4a slight pressure by the foot upon thelower -end l2 of thelever ll will release said lever and permit theharrow to descend. The upward movement of the suspending chains orcables will, -of course, cause the draft bars to swing upwardly inasmuchas the clevises will be thereby drawn against the under surfaces of thedraft bars and the rearwardly extending portions of the draft barswiththe runners pivoted thereto will be caused to yexert a lifting actionagainst the under surfaces of the harrow tooth bars V`so that theharrows will be raised and supported in raised position withoutrequiring excessive effort from the driver.

Having thus described the invention, what is .claimed as new is:

l. .An attachment for planters comprising a harrow, clevises extendingforwardlyV from the harrow, a rock shaft mounted upon the planter framezabove the harrow, means for actuating said rock shaft, draft barspivotally mounted on the planter frame andeX- tending through thelclevises and under the harrow, and means connected with and controlledby the 4rock shaft ffor liftingv the draft bars. i
